论文摘要
二进制中子星合并事件的多理智剂重力波（GW）观察可以提供一个相当有用的工具来探索宇宙的演变。特别是，对于第三代GW探测器，即爱因斯坦望远镜（ET）和宇宙资源管理器（CE），建议分别在欧洲和美国建造，可以获得许多带有已知重新换档的GW标准警笛，这将对宇宙学参数估计产生重大影响。总中微子质量可以通过宇宙学观测来测量，但是这种测量是模型依赖性的，目前仅给出上限。在这项工作中，我们希望研究ET和CE观察到的GW标准警笛是否可以帮助改善中微子质量的约束，特别是在相互作用的暗能量（IDE）模型中。我们发现，与当前极限相比，来自ET和CE的GW标准警笛观察只能稍微改善IDE模型中中微子质量的约束。 IDE模型的改进比标准宇宙学模型弱。尽管只能稍微更新中微子质量的限制，但通过使用GW观测值可以显着提高其他宇宙参数的约束。
The multi-messenger gravitational-wave (GW) observation for binary neutron star merger events could provide a rather useful tool to explore the evolution of the universe. In particular, for the third-generation GW detectors, i.e., the Einstein Telescope (ET) and the Cosmic Explorer (CE), proposed to be built in Europe and the U.S., respectively, lots of GW standard sirens with known redshifts could be obtained, which would exert great impacts on the cosmological parameter estimation. The total neutrino mass could be measured by cosmological observations, but such a measurement is model-dependent and currently only gives an upper limit. In this work, we wish to investigate whether the GW standard sirens observed by ET and CE could help improve the constraint on the neutrino mass, in particular in the interacting dark energy (IDE) models. We find that the GW standard siren observations from ET and CE can only slightly improve the constraint on the neutrino mass in the IDE models, compared to the current limit. The improvements in the IDE models are weaker than in the standard cosmological model. Although the limit on neutrino mass can only be slightly updated, the constraints on other cosmological parameters can be significantly improved by using the GW observations.
